Description

The present invention relates to an eaves arabesque that can prevent damage to the end portion of the heat insulating backup material disposed on the back surface of the exterior material before the arrangement of the horizontal roofing exterior material, and an eaves structure using the same.

Conventionally, in a horizontal roof, the exterior surface is formed by polymerizing (engaging) the underwater molded portion of the upper horizontal roofing exterior material and the lower water forming portion of the lower side. A heat insulating backup material made of expanded styrene is disposed on the back surface side of the exterior material, and these heat insulating backup materials are connected to each other to form a heat insulating layer. That is, in this heat insulating backup material, a protruding upper portion extending the surface layer portion (upper half) is formed on the lower side of the water, and a protruding lower portion extending the back layer portion (lower half) is formed on the upper side of the water. By polymerizing the upper part on the protruding lower part, a heat insulating layer without gaps can be formed.

Further, as the prior invention, the applicant has achieved double waterproofing between the heat insulating backup layer and the exterior surface by using the heat insulating backup material having the above-mentioned non-permeable structure, and the heat insulating backup material and the exterior surface. It has been found that it is highly integrated with the material and can be laid without using a hanger or the like (Japanese Patent Application No. 2017-57990).
The eaves are provided with members such as eaves arabesque and eaves material that prevent rain from reaching the eaves from the eaves to the back side due to capillarity.

For example, as a heat insulating material, Patent Document 1 describes a case where a roof is constructed from a separately molded roofing material and a heat insulating material, and the end portion of the heat insulating material is processed into a polymerizable shape and laid in a polymerized form. It has been proposed to obtain heat insulating performance and waterproofness by doing so. On the other hand, it is inevitable that the thickness of the end portion (processed portion) of the heat insulating material becomes thin, and it is necessary to pay sufficient attention to cracks and breakage when constructing the heat insulating material. Further, it has been proposed to mold a heat insulating (backup) material from expanded polystyrene or the like to form a non-permeable waterproof layer.
Further, as the gutter to be arranged at the eaves, in Patent Document 2, the eaves gutter 1 is suspended and held by the hanging tool 7 fixed to the fascia plate 10, and the upper end of the draining plate 2 corresponding to the cover material is used as the base of the roof. A fixed structure has been proposed.

However, even in the conventional horizontal roofing roof and the horizontal roofing roof of the above-mentioned invention, the heat insulating backup material is damaged during the construction when the construction of the heat insulating backup material is completed and the laying of the horizontal roofing exterior material is not completed. I sometimes did it. Especially on the bottom of the water (eaves), a space is formed on the back side of the upper part of the protrusion extending to the bottom of the water insulation backup material in the bottom of the water, so pressure from above (for example, work) as described above. It was easy to cause a damage accident when the person's shoe tip) acted.

Further, in a roof structure as in Patent Document 1, if the heat insulating material is cracked or damaged after being laid on the roof base, water leakage, heat insulating performance may be deteriorated, or construction of the exterior material may be difficult. Furthermore, there was a risk that debris would block the route as a waterproof layer and lead to water leakage.
Further, in Patent Document 2, since the upper end of the draining plate 2 corresponding to the cover material is fixed to the back surface side of the roofing material, it is necessary to attach the draining plate 2 before laying the roofing material. Was also a limitation.

Therefore, the present invention provides an eaves arabesque that can prevent damage to the end portion of the heat insulating backup material disposed on the back surface of the exterior material before the arrangement of the horizontal roofing exterior material, and an eaves structure using the same. The purpose is to make a proposal.

The present invention has been proposed in view of the above, and is an eaves Karakusa disposed on the eaves of a building, from a mounting fixing portion attached to the eaves tip of an exterior base (field material) and the mounting fixing portion. The eaves edge of the heat insulating backup material having an engaged portion extending to the eaves side to engage the eaves side molded portion of the exterior material and an eaves edge disposed on the back surface side of the exterior material and extending to the eaves side. A support portion that is a support portion that supports from the back surface side, and is composed of a first horizontal piece that extends to the side opposite to the eaves tip and a second horizontal piece in which the engaged portion is formed at the tip of the eaves. It is related to the eaves Karakusa, which is characterized by having.
The eaves edge of the heat insulating backup material is other than a configuration in which the eaves edge extends toward the eaves end, that is, a protruding upper portion having a surface layer portion (upper half) extending below the eaves is formed. do not have.

Further, the present invention is characterized in that the eaves arabesque is provided with a fixed portion for fixing the cover material covering the upper surface of the eaves gutter so as to project further toward the eaves side than the engaged portion. Also propose.

Further, the present invention also proposes an eaves structure characterized in that the eaves arabesque is attached to an exterior base and the eaves arabesque supports the eaves edge of a heat insulating backup material having an eaves edge extending toward the eaves side. ..

The eaves arabesque of the present invention can protect the eaves of a building and prevent damage to the end of the heat insulating backup material having the eaves extending to the eaves side during construction, for example.
In particular, since the support portion is composed of a first horizontal piece extending to the opposite side of the eaves and a second horizontal piece extending to the eaves side (an engaged portion is formed at the tip), the heat insulating portion is described above. The eaves edge of the backup material may be prevented from being damaged, and the first horizontal piece and the second horizontal piece may be made continuous so that the eaves edge of the heat insulating backup material protrudes in a substantially rectangular shape, or the first horizontal piece and the eaves edge may be adapted. The second horizontal piece may be combined in a stepped shape to adapt to a mode in which the eaves edge of the heat insulating backup material protrudes in two steps (protrudes in two steps).

Further, when the fixed portion for fixing the cover material covering the upper surface of the eaves gutter is provided so as to project further toward the eaves side than the engaged portion, the cover material is further bent downward and inward at the eaves tip. By providing a substantially U-shaped engaging portion and engaging the eaves tip of the eaves gutter on the back surface side thereof, the cover material also serves as an arm for holding the eaves tip of the eaves gutter so as to pull it.

Further, in the eaves structure of the present invention, the eaves arabesque is attached to the exterior base, and the eaves arabesque supports the eaves edge of the heat insulating backup material, so that the end portion of the heat insulating backup material is prevented from being damaged as described above. It can be done.

(A) A side view showing an enlarged exterior material (horizontal roofing exterior material) used for the eaves structure of the first embodiment, (b) a state in which the exterior material is laid on a part of the heat insulating backup material connected in the flow direction. It is a side sectional view showing a state in which an exterior material is laid on a part of a heat insulating layer formed on an exterior base (field material), and arabesque at the eaves is attached to the eaves edge.

The eaves Karakusa of the present invention is an eaves Karakusa disposed on the eaves of a building, and has a mounting fixing portion attached to the eaves tip of an exterior base (field material) and extending from the mounting fixing portion to the eaves side. Supports the eaves edge of the heat insulating backup material having an engaged portion for engaging the eaves side molded portion of the exterior material and an eaves edge disposed on the back surface side of the exterior material and extending to the eaves front side from the back surface side. A support portion including a first horizontal piece extending to the opposite side of the eaves and a second horizontal piece on which the engaged portion is formed at the tip of the eaves. It is a feature.

Prior to the explanation of each part of the eaves arabesque, the eaves end extending to the eaves side of the heat insulating backup material will be described. It is none other than the configuration in which the existing protruding upper part is formed.

The mounting and fixing portion is a portion to be mounted on the eaves tip of an exterior base such as a field material, and may have any shape as long as it can be mounted on the exterior base to be mounted.
For example, in the illustrated embodiment described later, the eaves edge of the field material having a substantially rectangular cross section is formed into a substantially U-shape that can be fitted from the eaves side, but the present invention is not particularly limited to this. In addition, a fixing tool such as a screw may be driven in from above to firmly fix it, or if it is formed in a substantially U-shape, it can be attached to the eaves edge of the exterior base in a fitted shape, improving workability. However, the mounting strength is also improved.

The engaged portion is a portion extending from the mounting and fixing portion to the eaves side to engage the eaves side molded portion of the exterior material, and any of the above can be engaged with the eaves side molded portion of the exterior material. It may have such a shape.
Further, the exterior material to be engaged with the engaged portion may be, for example, a horizontal roofing exterior material or a vertical roofing exterior material, and in the former case, the exterior material may be engaged with the eaves side molded portion of the horizontal roofing exterior material at the end of the eaves. Alternatively, in the latter case, the eaves edge of the vertically-roofed exterior material may be folded back toward the back surface to engage with the exterior material.

Further explaining the case where the eaves molded portion to which the engaged portion is engaged is a horizontal roofing exterior material, the connecting portion between the exterior materials adjacent to each other in the flow direction is formed on the eaves side molded portion of the exterior material on the water side. On the other hand, the ridge-side molded part on the underwater side is engaged, but since there is no engaging partner in the eaves-side molded part of the exterior material on the eaves side, which is arranged on the most underwater side, the eaves of Karakusa is covered. The engaging portion becomes the engaging partner. For example, in the illustrated embodiment described later, the tip of the horizontal piece facing the eaves (second horizontal piece) is used, but the present invention is not particularly limited to this.

The support portion supports the eaves end extending to the eaves side of the heat insulating backup material from the back surface side, and may have any shape as long as it can contact the eaves edge shape of the heat insulating backup material from the back surface.
For example, if the eaves edge of the heat insulating backup material protrudes in a substantially rectangular shape, the support portion for supporting the heat insulating backup material may be a substantially horizontal horizontal support piece, as in the illustrated embodiment described later. If the eaves edge of the heat insulating backup material protrudes in two steps (protrudes in two steps), the support portion for supporting the heat insulating backup material may be a stepped L-shaped support piece.

For example, in the illustrated embodiment described later, the support portion is divided into a first horizontal piece extending toward the exterior material side and a second horizontal piece extending toward the eaves side and having an engaged portion formed at the tip thereof. Therefore, if the first horizontal piece and the second horizontal piece are formed (arranged) in the same linear shape, the above-mentioned substantially horizontal horizontal support piece can be obtained, and the first horizontal piece and the second horizontal piece can be formed. If it is formed (arranged) in a stepped shape, the above-mentioned stepped L-shaped support piece can be obtained, but the present invention is not particularly limited to this.

The eaves to which the eaves arabesque of the present invention is attached is the eaves tip of an exterior base material such as a field material, and an exterior material having a heat insulating backup material disposed on the back surface side is laid on the exterior base, and the heat insulating backup is provided. As long as the eaves edge of the material extends to the eaves side, the specific configuration thereof is not particularly limited.

As long as the heat insulating backup material has a structure in which the eaves end extends to the eaves side as described above, the specific structure thereof is not particularly limited, but the illustrated examples described later will be described. It is desirable to provide a structure in which the ridge end extends to the ridge side so that the heat insulating backup materials adjacent to each other in the flow direction can be connected in a staggered manner. That is, the heat insulating backup material has a protruding upper portion (upper polymerization portion) on which the surface layer portion (upper half) extends, and a back layer portion (lower half) on the water upper end thereof. This is because when the configuration is provided in which an extending protruding lower portion (lower overlapping portion) is formed, the protruding upper portion can be polymerized on the protruding lower portion, and a heat insulating layer having no gap in the flow direction can be formed.

Further, the heat insulating backup material is preferably impermeable to water, specifically, a foamed heat insulating backup material, particularly a material having some elasticity, for example, a single layer of a synthetic resin such as expanded polystyrene and foamed polyethylene. Alternatively, it is preferable to use a laminated body. This impermeable, effervescent heat insulating backup material is a material in which air bubbles are independently and randomly present, so that impermeableness is always ensured even if processing such as cutting is performed. desirable. This is because the above-mentioned "heat insulating layer without gaps" can be used as a "waterproof layer without gaps".

Further, the surface of the heat insulating backup material may be flat or may have grooves. The groove is a drainage groove for draining dew condensation water or the like before or after laying the exterior material to the underwater side without staying on the heat insulating backup material, and is not limited to the flow direction. The phased part (side edge) may be "diagonal" facing inward (to prevent water from wrapping around the side edge).
Further, the back surface of the heat insulating backup material may also be flat, or a space (gap) may be provided by forming protrusions, grooves, or the like. The formed space (gap) enables air to flow to and from the base material.

The exterior material is a horizontal roofing exterior material that is laid on the heat insulating layer and has an eaves-side molded portion at its lower end, and its specific configuration including the eaves-side molded portion is particularly limited. A known metal material such as a surface decorative steel plate, a laminated steel plate, a plated steel plate, a stainless steel plate, an aluminum alloy plate, a titanium alloy plate, and a copper plate, which is typically about 0.4 to 1.6 mm, is roll-formed. A product molded into a predetermined shape by extrusion molding or other means can be appropriately used. Further, the back surface of the exterior material may be provided with a backing material such as polyethylene foam or glass wool sheet, if necessary, for reasons of dew condensation prevention, soundproofing, and fire prevention measures.

As described above, the protruding upper portion of the heat insulating backup material is a portion where the surface layer portion (upper half) of the lower end of the water extends to the lower side of the water. The molded portion may be fitted. That is, in many horizontal-roofed exterior materials, an eaves-side molded portion is engaged with and connected to a ridge-side molded portion on a substantially flat heat insulating layer, and the engaged portion is fixed on the heat insulating layer, such as a hanger. However, by providing a portion to be fitted to the protruding upper part as the water upper side (ridge side) molding part, the water flow direction without the need for a hanger. It is possible to connect adjacent exterior materials to each other.
The exterior material in the above-mentioned prior invention (Japanese Patent Application No. 2017-57990) has a fixed piece portion along the water-insulating backup material on the water upper side of the face plate portion, and the water bottom side is open on the water bottom side thereof. It is possible to engage with the lateral groove by folding it back to the back surface side and extending it to the water upper side with the water upper molded portion having a lateral groove and a fitting portion fitted to the protruding upper portion of the heat insulating backup material. Since it is provided with a structure having a plug-in piece and a underwater molded portion having a polymerization portion to be polymerized on the outside of the fitting portion, this exterior material may be used.

Further, the eaves arabesque of the present invention may be provided with a fixed portion for fixing the cover material covering the upper surface of the eaves gutter so as to project further toward the eaves side than the engaged portion.
The cover material is a member that covers the upper surface of various eaves gutters and is a member that prevents snow and dust from entering the eaves gutter. It is desirable that a slit hole is formed.
The shape of the bottom surface and both side surfaces of the eaves gutter whose upper surface is covered with this cover material is not particularly limited as long as it has a drainage channel for rainwater or the like inside. For example, vinyl chloride, polycarbonate, etc. Since the general-purpose product may be used, the configuration and shape of the cover material covering the upper surface thereof are not particularly limited.

As described above, the fixed portion is a portion for fixing the cover material covering the upper surface of the eaves gutter so as to project further toward the eaves side than the engaged portion. In addition, the above-mentioned "protruding further toward the eaves side than the engaged portion" means that the fixed portion is positionedly projected toward the eaves side from the engaged portion.
The fixed portion can be formed in a horizontal piece shape or a vertical piece shape, and the cover material can be fixed by using a fixing tool such as a screw.

As described above, the shape and the like of the cover material and the eaves gutter are not particularly limited. When a character-shaped engaging portion is provided and the eaves tip of the eaves gutter is engaged on the back surface side thereof, the substantially U-shaped engaging portion pulls the eaves tip of the eaves gutter from above. It can be held in and bear the load of the eaves gutter. That is, the cover material in this case also serves as an arm that pulls and holds the eaves tip of the eaves gutter.

As described above, the eaves arabesque of the present invention is a member provided with a mounting fixing portion, an engaged portion, and a supporting portion, and has a strength characteristic for preventing the eaves edge of the heat insulating backup material from bending downward and being damaged. The material, processing method, and the like are not particularly limited as long as the material is provided, but the mounting and fixing portion, the engaged portion, and the supporting portion are formed as continuous continuous materials in the length direction. It is desirable from the viewpoint of protecting the eaves.
Moreover, this eaves arabesque is attached to the roof surface (roof structure) such as the exterior base, and unlike the conventional gutter receiving metal fittings mentioned above, the fasteners are not driven into the fascia wall surface from the side, so it is easy. Moreover, it can be firmly attached.
